Ultrasound can reduce friction in deep drawing and thus protect ... plus the blank holder that keeps the sheet metal in the desired position during forming, are all viable. The researchers chose ...

Small cylindrical parts are often formed through deep drawing — a process by which a punch forms the finished piece from a flat sheet of metal using a forming die. If it sounds like that ...

Sheet metal is very easy to form, including the pressing in of intricate shapes with dies and a hydraulic press, but the dies themselves are slightly harder to come by. What if we could 3D print ...
